Written while waiting for tests to pass, just watchin' my ascii snail cross the screen to pass the time.

snail.js

var snail = '@__y'
  , progress = 0
  , pad = function(x) { var str = []; for(var i = 0; i < x; ++i) { str.push(' ') }; return str.join('') }

var interval = setInterval(function() {
  ++progress
  progress >= 100 &&
    (progress = 0)

  process.stdout.write('\r')
  process.stdout.write(pad(progress)+snail+pad(100-progress))
}, 400)

process.on('SIGINT', function() {
  clearInterval(interval)
  process.stdout.write('\n')
  setTimeout(function() { process.exit() }, 0)
})
